INSTALLATON

WHERE AND HOW TO MOUNT YOUR DEVICE

1. You should choose the most appropriate setting from a simple and practical point of view.
2. Your radio should not interfere with the driver or the passengers.
3. Remember to provide different wires for passing and protection. (e.g.: power, antenna, accessory cabling) so that they do not in any way interfere with the driving of vehicles.
4. To install your equipment, use the cradle (1) and the self-tapping screws [2] provided (drilling diameter 5 mm). Take care not to damage the vehicle's electrical system while drilling the dash board.
5. Do not forget to insert the rubber joints [3] between the TX and its support as these have a shock-absorbing effect which permits gentle orientation and tightening of the set
6. Choose where to place the microphone support and remember that the microphone cord must stretch to the driver without interfering with the controls of the vehicle.

ANTENNA INSTALLATION

1. Choosing your antenna:
   For radios, the longer the antenna, the better its results. Your dealer will help you with your choice of antenna. b) Antena Movel.
2. Mobile antenna:
   • Must be fixed to the vehicle where there is a maximum Of metallic surface(ground plane), away from windscreen mountings.
   • There are two types of antenna: Pre-Regulated Antenna which should be used on a good ground plane (e.g. car roof or lid of the boot), and Adjustable Antenna which offer a much larger frequency range and can be used on a smaller ground plane.
     For an antenna which must be fixed by drilling, you will need a good contact between the antenna and the ground plane. To obtain this, you should lightly scratch the surface where the screw and tightening star are to be placed
   • Be careful not to pinch or flatten the coaxial cable (as this runs the risk of break down and/or short circuiting).
   • Connect the antenna to location (B).
3. Fixed antenna:
   A fixed antenna should be installed in a space as clear as possible. If it is fixed to a mast, it will perhaps be necessary to stay it, according to the laws in force (you should seek professional advice). All SS 6900 antennas and accessories are designed to give maximum efficiency to each radio within the range.
   

POWER CONNECTION

Your RADIO is protected against an inversion Of polarities. However before switching it on, you are advised to check all the connections. Your equipment must be supplied with a continued current of 12 volts (A). Today, most cars and lorries are negative earth. You can check this by making sure that the negative terminal of the battery is connected either to the engine block or to the chassis. If this is not the case, you should consult your dealer.

Lorries generally have two batteries to supply a voltage Of 24 volts, in which case it will be necessary to insert a 24/12 volt converter into the electrical circuit. The following connection steps should be carried out with the power cable disconnected from the set.

1. Check whether the battery is of 12 volts.
2. Locate the positive and negative terminals of the battery (+ is red and - is black). Should it be necessary to lengthen the power cable, please use the same or a superior type of cable,
3. lt is necessary to connect your TX to a permanent and (-). We advise you to connect the power cable directly to the battery (as the connection of the TX cable to the wiring of the car-radio or other parts of the electrical circuit may, in some cases, increase the possibilities of interference).
4. Connect the red wire (+) to the positive terminal of the battery and the black (-) wire to the negative terminal of the battery.
5. Connect the power cable to your radio.

Never replace the original fuse (10A) by one of a different value.

BASIC OPERATIONS TO BE CARRIED OUT BEFORE USING YOUR SET FOR THE FIRST TIME

(without transmitting or using the <<Push-To-Talk>> switch on the microphone)

1. Connect the microphone
2. Check the antenna connections
3. Turn the set on by turning the volume knob clockwise
4. Tum the squelch knob to minimum
5. Adjust the volume to a comfortable level
6. Go to channel 20 D band by using either the UP or DN key on the microphone or the rotary knob,

ADJUSTMENT OF SWR

(standing wave ratio)

This must be carried out when you use your radio for the first time (and whenever you re-position your antenna). The adjustment must be carried out in an obstacle-free area.

Adjustment with a built-in SWR meter or external SWR meter

1. To connect the SWR meter Connect the SWR meter between the radio and the antenna as close as possible to the radio (use a maximum of 40cm cable).
2. To adjust the SWR meter
   • Set the TX to channel 20 D band in FM.
   • Put the switch on the SWR meter to position CAL or FWD.
   • Press the <<Push-To-Talk>> switch on the microphone to transmit.
   • Bring the index needle to by using the calibration key.
   • Change the switch to position SWR (reading of the SWR level).
     The reading on the meter should be as near as possible to 1. If this is not the case, re-adjust your antenna to obtain a reading as close as possible to 1.(An SWR reading between 1 and 1.8 is acceptable).
   • It will be necessary to re-calibrate the SWR meter after each adjustment of the antenna.

HOW TO USE INTERNAL SWR METER

• Set TX to channel 20 D band in FM.
• Press <<Push-to-talk>> button on the microphone to transmit.
• At the moment, LCD would display SWR value which should be as close as possible to 1. If this is not the case, re-adjust your antenna to obtain a SWR value as close as possible to 1 (an SWR reading between 1 and 1.8 is acceptable).
